The precision grinding of the gears is carried out in the overall rapid deep grinding of the workpiece, which significantly improves the production efficiency of the gears in the service life, thereby improving the economics of processing and production: by greatly reducing the adjustment time during processing operations and The adjustment of the meaning of the feed, thereby improving the service life of the gear precision grinding.

In the process of precision gear grinding of gears, most of the blanks are subjected to isothermal normalizing after forging, in order to obtain a good metallographic structure with good processing performance and trend deformation; for low-speed net-column gears with low precision requirements, hot front shaving can be performed. After the heat is no longer processed, the application of the radial shaving method expands the range of shaving applications; the cylindrical gears are post-heated with two methods of caries and grinding, the cost of the teeth is low but the tooth shape correction ability is weak, and the grinding accuracy is High and high cost; the use of the tooth tip trimming along the tooth height direction and the drum tooth shaping process along the tooth length direction can significantly reduce the gear meshing noise and improve the transmission performance, and is a research field that has been widely concerned.

Among them, gear hot post processing has two kinds of grinding teeth and grinding teeth. Due to the high cost, low efficiency and limitation of grinding gear, most of the grinding teeth are used at present, and the geometric correction ability of the grinding teeth is very weak, so according to the above understanding, we It can be known that gear precision grinding has high requirements for the use of gears and its accuracy.

Thanks to China's economic growth, the domestic machine tool industry has made rapid progress in recent years. At the same time, China is also the world's largest consumer and importer of machine tools. In terms of market demand, with the strong development momentum of a number of high-growth industries based on heavy industry such as domestic automobile, steel, machinery, mold, electronics and chemical industry, the demand for efficient and high-precision automated manufacturing equipment, machine tool industry Enter the stage of rapid growth. From the perspective of imported models, precision production, high-efficiency and high-speed CNC machine tools, machine tool remanufacturing demand has increased significantly, showing that China's machine tool demand structure has undergone a major change. However, important parts that affect the development of machine tools are also indispensable, that is, precision machine tool gears.

Gears and racks are commonly used in our transmission machinery. The manufacturing process and the production of other teeth are special. Next, we will take a look at the processing technology of the gear shaping! The gear shaping is a method of machining the inner and outer gears or racks by means of a pinion cutter.

1. The tooth profile accuracy of the pinion is higher than that of the hobbing. This is because the shaper cutter can be used to obtain a precise involute profile through the precision gear grinding machine.

2. The tooth surface roughness value after tooth insertion is smaller than the hobbing tooth. The reason is that the circumferential feed amount of the gear teeth is usually small, and the number of cutting edges of the envelope tooth surface is larger than that of the hobbing teeth during the tooth insertion process, so that the tooth surface roughness after the tooth insertion is small.

When cutting a gear with a large modulus, the gear insertion speed is restricted by the rigidity of the reciprocating inertia bed of the main shaft of the gear insert, and the cutting process has a loss of the idle time, so the productivity is lower than that of the hobbing.加工 When machining small gears with small modulus, gears, and narrow teeth, the pinion productivity will be higher than the hobbing.

I don't know what to say in the righteousness. Do you have any further understanding of the shaping of the gears? Presumably this should be inevitable!

The design of precision machine tool gears is an important form of gear transmission, which can be widely used in various fields of machine manufacturing. However, different types of precision machine tool gears have different applications. The gear can be divided into the following three categories in terms of axial and positional relationship:

The first category: parallel axis classes, parallel axis classes are divided into the following:

The third category: offset axis class, offset axis class has the following:

[1], cylindrical worm gear: cylindrical worm gear is the general term for worm and gear.

[2], misaligned helical gear: It is a cylindrical helical gear that requires the use of a transmission between the wrong axes.

[3] Face gear: A disk-shaped gear that can be engaged with a spur gear or a helical gear.

[4], drum-shaped worm gear: a general term for a concave drum worm and a gear that meshes with it.

Therefore, in summary, the above three categories have their own advantages and use different places. Therefore, when using various types of gears, you should look at the type of gears you need to prevent yourself from choosing. Wrong, resulting in the installation of mechanical equipment can not be used.
